382 CORK INSULATION at the daily expense of labor and ice ; and some improvement I may be effected by the manufacturer through a change in { the interior design of the refrigerator that will locate the ice compartment in a top-center position, and at no additional expense; but by increasing the thickness of permanently effi- cient <strong>insulation</strong> in the walls of the refrigerator, at a low per- > centage of increase in manufacturing cost, the food compartment may be so effectively isolated from outside heat influ- ences as to make the maintenance of correct temperatures by the melting of ice a practical matter even on the hottest and the most humid days of the year. Experience has safely fixed this <strong>insulation</strong> at three inches of pure corkboard, when prop- erly incorporated in the construction of the refrigerator. From these few observations, it would appear to be of but limited value to test poorly designed and badly constructed refrigerators that are to be cooled with ice. Consequently, the first point to cover in planning for a test of an ice refrigerator should be a careful investigation into the design and construction of the unit; and if this research reveals a lack of reasonable consideration for basic principles of design and construction, as they are then generally known and under- stood, there probably will be good reason to abandon the intention to perform the test. Otherwise, the following test conditions should be observed : (a) Refrigerators of identical shape and size must be selected for comparative test purposes. It is suggested that standard sizes be determined upon for a top-icer apartment refrigerator, a side-icer small residence refrigerator and a center-icer large residence refrigerator, and that all future tests be run on refrigerators as near those sizes as possible. (b) A constant temperature room should be used, the temperature held uniform to within one degree Fahr. by electric heater placed within hollow walls of the test room and controlled by thermostat. A room temperature of at least 85° F. is suggested for test purposes. (c) Control of the humidity of the constant temperature room should be effected by suitable means, tests having demonstrated that a consider- able increase in the percentage of ice melting is effected by increasing the percentage of relative humidity in a constant temperature room from a low to a high point. (d) The ice should be carefully regulated on the basis of weight, and of one piece, of size or shape suitable for the ice compartment of the class of unit tested. (e) The ice should be only hard, "black" ice. j
CORKBOARD INSULATED REFRIGERATOR 383 (f) The ice should be prepared outside the test room, and placed in the refrigerator during a fixed period, at the same hour, every day (24- hour icing), old ice to be removed and weighed simultaneously. (g) The food compartment of the refrigerator should be empty, it being known that over 90 per cent, of refrigerator losses are caused by the heat leakage through the walls of the refrigerator, and less than 10 per cent, in cooling food and opening doors, under normal household operation. (h) Record of refrigerator temperatures should be made every hour, by suitable means, such record to be taken at three designated points in
